Description

Technical Field

[0001] This utility model relates to the field of meter reading technology, and in particular to a shockproof shell structure for a handheld meter reading device. Background Technology

[0002] With the popularization of smart grids and information management, handheld meter readers, as a common data collection tool in industries such as electricity, gas, and water supply, are widely used in outdoor field operations. Existing handheld meter readers are small and portable, but they often need to be operated in outdoor environments and are greatly affected by external climate, temperature, and environmental conditions.

[0003] High temperatures in summer can easily cause the internal temperature of meter readers to rise, affecting their normal operation and lifespan. Furthermore, since meter readers are inevitably subject to drops and impacts during field operations, existing protective measures are mostly based on rigid casings, offering limited shock absorption and drop protection. This can easily damage internal electronic components, thereby affecting the accuracy of data collection and the reliability of the equipment. Utility Model Content

[0004] This utility model provides a drop-proof shell structure for a handheld meter reader. It uses a weightlessness sensor to detect weightlessness and triggers an electric air pump to inflate the airbag. The elasticity of the inflated airbag reduces the vibration of the meter reader, thus solving the problem of damage to internal components caused by drops and impacts.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a drop-proof outer shell structure for a handheld meter reader, comprising: a first protective shell and two airbags; a second protective shell, detachably connected to the inside of the first protective shell; an L-shaped block, fixedly connected to the bottom of the second protective shell, wherein a threaded rod is movably embedded inside the L-shaped block, and one of the protrusions has multiple locking holes at its bottom, the threaded rod being movably embedded inside one of the locking holes of the protrusion; two airbags are respectively fixedly installed on one side of the outer surface of the first and second protective shells; two protrusions are fixedly connected to one side of the first protective shell; a weightlessness sensor is fixedly installed on one side of the first protective shell, and an electric air pump is fixedly connected to the side of the first protective shell near the weightlessness sensor, wherein two air tubes are fixedly installed at the output end of the electric air pump, and one end of each of the two air tubes is fixedly connected to the inside of the two airbags.

[0006] The technical effect of adopting the above-mentioned further solution is as follows: During the process of the equipment falling, the weightlessness sensor detects weightlessness and transmits the signal to the electric air pump through the wire. At this time, the electric air pump is started to inflate the inside of the two air bladders through the two air pipes. After the surrounding air bladders are inflated, they can protect the entire protective shell. When the device falls to the ground, the surrounding air bladders have a certain degree of elasticity, which can reduce the vibration of the internal meter reader and prevent the internal components from being damaged due to large vibrations.

[0007] In a preferred embodiment, a cover is rotatably connected to the top of the first protective shell via a hinge. A first magnet is fixedly installed on one side of the cover, and a second magnet is fixedly installed on the top of the first protective shell. The second magnet is connected to the first magnet. Two grooves are formed on the inner wall of the second protective shell. A sealing ring is provided at the bottom of the cover to improve the sealing at the connection with the first protective shell.

[0008] The technical effect of adopting the above-mentioned further solution is that the cover can be closed and opened. At this time, the first magnet and the second magnet attract each other to limit the cover. When the meter reader is not in use, the cover can be closed to protect it from dust and rain.

[0009] In a preferred embodiment, the two protrusions are located inside the two grooves.

[0010] The technical effect of adopting the above-mentioned further solution is that the two protrusions slide inside the two grooves, and when the threaded rod at the bottom of the second protective shell is embedded in one of the locking holes, it can be adjusted and limited.

[0011] In a preferred embodiment, the bottom of the first protective shell is detachably connected to a base plate, a cooling fan is rotatably connected inside the base plate, and a dustproof mesh is detachably connected to the bottom of the base plate.

[0012] The technical effect of adopting the above-mentioned further solution is that the rotation of the cooling fan can dissipate heat from the meter reader, preventing the meter reader from becoming less efficient when used outdoors due to high ambient temperatures.

[0013] In a preferred embodiment, the dust filter is located at the bottom of the cooling fan.

[0014] The technical effect of adopting the above-mentioned further solution is that the dustproof net has a certain dustproof effect, preventing excessive dust inside the fan.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, during the process of the device falling, the weightlessness sensor detects weightlessness and transmits the signal to the electric air pump through the wire. At this time, the electric air pump is started and inflates the inside of the two air bladders through two air pipes. After the surrounding air bladders are inflated, they can protect the entire protective shell. When the device falls to the ground, the surrounding air bladders have a certain degree of elasticity, which can reduce the vibration of the internal meter reader and prevent the internal components from being damaged due to excessive vibration.

[0017] 2. In this utility model, the meter reader is placed inside the first protective shell, and then the second protective shell is embedded into the hole of the first protective shell. Then, the threaded rod is rotated to move inside the L-shaped block. At this time, the threaded rod is embedded inside one of the locking holes, and the protrusion moves inside the groove. The size between the first and second protective shells can be adjusted, and the length can also be adjusted to adapt to meter readers of different sizes. The cover can be closed and opened. At this time, the first magnet and the second magnet attract each other to limit the cover. When the meter reader is used inside, the cooling fan rotates to dissipate heat from the meter reader, preventing the meter reader's efficiency from decreasing due to high outside temperatures when used in the field.

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Please see Figures 1 to 4 This utility model provides a drop-proof outer shell structure for a handheld meter reader, including: a first protective shell 101 and two airbags 106; a second protective shell 102, detachably connected to the inside of the first protective shell 101; an L-shaped block 115, fixedly connected to the bottom of the second protective shell 102, with a threaded rod 116 movably embedded inside the L-shaped block 115; a plurality of locking holes 117 are opened at the bottom of one of the protrusions 113, and the threaded rod 116 is movably embedded inside one of the locking holes 117 of the protrusion 113; the two airbags 106 are respectively fixedly installed on one side of the outer surface of the first protective shell 101 and the second protective shell 102; specifically, the two airbags 106 are symmetrically distributed along the circumference of the protective shell, and after inflation, they cover the perimeter of the shell to form a 360-degree protective layer; the two protrusions 113 are fixedly connected to one side of the first protective shell 101. A weightlessness sensor 108 is fixedly installed on one side of the first protective shell 101. An electric air pump 107 is fixedly connected to the side of the first protective shell 101 near the weightlessness sensor 108. Two air pipes 109 are fixedly installed at the output end of the electric air pump 107. One end of each air pipe 109 is fixedly connected to the inside of two air bags 106. During the fall of the device, the weightlessness sensor 108 senses weightlessness and transmits the signal to the electric air pump 107 through wires. At this time, the electric air pump 107 is started to inflate the inside of the two air bags 106 through the two air pipes 109. When the surrounding air bags 106 are inflated, they can protect the entire protective shell. When the device falls to the ground, the surrounding air bags 106 have a certain degree of elasticity, which can reduce the vibration of the internal meter reader and prevent the internal components from being damaged due to excessive vibration. In one specific embodiment, during the device drop, the weightlessness sensor 108 transmits an electrical signal in real time via an embedded wire (specifically connected to the control port of the electric air pump 107); the electric air pump 107 starts within 50 milliseconds after receiving the signal and inflates the airbag 106 through two air tubes 109 to ensure that inflation is completed within 200 milliseconds.

[0026] The top of the first protective shell 101 is connected to a cover 103 via a hinge. A first magnet 104 is fixedly installed on one side of the cover 103, and a second magnet 105 is fixedly installed on the top of the first protective shell 101. The second magnet 105 is connected to the first magnet 104. Two grooves 114 are opened on the inner wall of the second protective shell 102. The cover 103 can be closed and opened. At this time, the first magnet 104 and the second magnet 105 attract each other and limit the cover 103. When the meter reader is not in use, the cover 103 can be closed to protect it from dust and rain.

[0027] Two protrusions 113 are located inside two grooves 114. The two protrusions 113 slide inside the two grooves 114. When the threaded rod 116 at the bottom of the second protective shell 102 is embedded in one of the locking holes 117, it can be adjusted and limited.

[0028] A base plate 110 is detachably connected to the bottom of the first protective shell 101. A cooling fan 111 is rotatably connected inside the base plate 110, and a dustproof mesh 112 is detachably connected to the bottom of the base plate 110. In one specific embodiment, the base plate 110 is detachably connected to the bottom of the first protective shell 101 via a snap-fit ​​structure; the cooling fan 111 is connected to the meter reader's power supply via an internal circuit and is automatically controlled to start and stop by a temperature sensor; the dustproof mesh 112 is magnetically fixed below the cooling fan 111. The rotation of the cooling fan 111 dissipates heat from the meter reader, preventing reduced efficiency due to high ambient temperatures when used outdoors.

[0029] The dust filter 112 is located at the bottom of the cooling fan 111. The dust filter 112 has a certain dustproof effect, preventing the fan from accumulating too much dust inside.

[0030] Working principle: When in use, the meter reader is placed inside the first protective shell 101, and then the second protective shell 102 is inserted into the hole of the first protective shell 101. Then, the threaded rod 116 is rotated to move inside the L-shaped block 115. At this time, the threaded rod 116 is embedded in one of the locking holes 117, and the protrusion 113 moves inside the groove 114. The size between the first protective shell 101 and the second protective shell 102 can be adjusted, and the length can also be adjusted to adapt to meter readers of different sizes. Specifically, the threaded rod 116 is rotated to move axially within the L-shaped block 115. When the protrusion 113 slides to the target position in the groove 114, the end of the threaded rod 116 is screwed into the corresponding locking hole 117 to lock it, thus completing the size adjustment. The cover 103 can be closed and opened. At this time, the first magnet 104 and the second magnet 105 attract each other to limit the cover 103. When the meter reader is used inside, the cooling fan 111 rotates to dissipate heat from the meter reader, preventing the meter reader's efficiency from decreasing due to high outside temperatures when used in the field. At the same time, during the drop of the device, the weightlessness sensor 108 senses weightlessness and transmits the signal to the electric air pump 107 through the wire. At this time, the electric air pump 107 is started to inflate the inside of the two air bags 106 through the two air tubes 109. When the surrounding air bags 106 are inflated, they can protect the entire protective shell. When the device falls to the ground, the surrounding air bags 106 have a certain degree of elasticity, which can reduce the vibration of the internal meter reader and prevent the internal components from being damaged due to excessive vibration.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
